Iobit: community verdicts

In IOBit IOTransfer 4.3.1.1561, an unauthenticated attacker can send GET and POST requests to Airserv and gain arbitrary read/write access to the entire file-system (with admin privileges) on the victim's endpoint, which can result in data theft and remote code execution.

IOBit Advanced System Care 15, iTop Screen Recorder 2.1, iTop VPN 3.2, Driver Booster 9, and iTop Screenshot sends HTTP requests in their update procedure in order to download a config file. After downloading the config file, the products will parse the HTTP location of the update from the file and will try to install the update automatically with ADMIN privileges. An attacker Intercepting this communication can supply the product a fake config file with malicious locations for the updates thus gaining a remote code execution on an endpoint.

The iTopVPNmini.exe component of iTop VPN 3.2 will try to connect to datastate_iTopVPN_Pipe_Server on a loop. An attacker that opened a named pipe with the same name can use it to gain the token of another user by listening for connections and abusing ImpersonateNamedPipeClient().

IOBit Advanced System Care (Asc.exe) 15 and Action Download Center both download components of IOBit suite into ProgramData folder, ProgramData folder has "rwx" permissions for unprivileged users. Low privilege users can use SetOpLock to wait for CreateProcess and switch the genuine component with a malicious executable thus gaining code execution as a high privilege user (Low Privilege -> high integrity ADMIN).

In IOBit Advanced System Care (AscService.exe) 15, an attacker with SEImpersonatePrivilege can create a named pipe with the same name as one of ASCService's named pipes. ASCService first tries to connect before trying to create the named pipes, because of that during login the service will try to connect to the attacker which will lead to either escalation of privileges (through token manipulation and ImpersonateNamedPipeClient() ) from ADMIN -> SYSTEM or from Local ADMIN-> Domain ADMIN depending on the user and named pipe that is used.
